Dear friend
Our 33772 has a zero drift of 18mv when collecting voltage with GPIO0。What causes it?I need help,Thanks.

Hello Jing,
How is your GPIO0 configured and have you tested other GPIOs?
To diagnose the exact cause, consider performing a detailed analysis of the circuit, including measuring the actual input signal, checking the stability of the reference voltage and reviewing the PCB layout for potential issues.
